JOHN HORINEK, OF ATWOOD, KANSAS.

BELT-REPLACER.

To all whom it may concern:

Be it known that 1, JOHN HORINEK, a citizen of the United States, residing at Atwood, in the county of Rawlins and State of Kansas, have invented certain new and useful Improvements in Belt-Replacers, of which the following is a specification.

The present invention appertains to means for placing the drive belt of traction engines upon the belt pulley. Usually this operation is effected by hand and entails considerable effort besides endangering the life and limb of the party or persons engaged in such operation.

Field machinery, such as separators, threshers, hay stackers and the like are erated by means of a traction engine, tie power being transmitted from the latter to the former by means of a drive belt which is heavy and difficult of management, particularly when placing said drive belt upon the drive pulley of the engine.

The present invention supplies a mechanism which, in one position, receives the belt, which being slack may be easily and quickly fitted to the supporting arms, said mechanism being of such construction as to simultaneously spread the runs of the drive belt and slip the same upon the drive pulley, without requiring the attendant to run any risk or danger, whatsoever, the operating parts being moved by means of a hand lever.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the detailsof construction and the means for efi'ecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side view of a traction engine, provided with belt replacing means embodying the invention.

tions of the operating bar. Fig. 8 is a detail perspective view of a portion of the detent for holding the belt supporting arm in operative position. Fig. 9 is a section on the line 22 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The traction engine 1 may be of any make or variety and equipped with an engine of any type having a drive pulley 2 around which the drive belt 3 passes, said drive belt serving to transmit motion from the engine to the machinery to be driven. An operating bar 4 is arranged at one side of the engine and is mounted to slide in suitable keepers 5 which retain it in place and give direction to its movements. A hand lever 6 has connec tion with the operating bar 4 and is provided with the usual latch bolt to cooperate with the teeth of a notched bar '7 to hold the oper ating bar and parts connected. therewith in the re uired position. A longitudinally slotted ink 8 has pivotal connection with the end of the bar 4 remote from the lever 6 and. serves to limit the movements of said bar and to prevent displacement thereof. A second link 9 is likewise pivotally connected to the end of the bar 4 and supports the rear end of the same and assists materially in holding it in proper position.

A bracket 10 is attached to a side of the engine and adjustably supports arms 11. and 12 which in turn support the frame of the belt replacer. 'This frame, as shown most clearly in Fig. 2, is approximately of V-form and is mounted upon the operating bar 4 so as to move therewith. A brace 13 connects the outer end of the frame with the operating bar to provide a more substantialconstruction. The frame comprises a lower member 14 and an upper member 15, the latter hav ing a pivota movement which is essential, as will appear more fully hereinafter. The two members 14 and 15 are of similar formation, each being constructed of a channel or U iron, the members being arranged with the hollow sides facing inward. Longitudinal slots 16 are formed in the flanges of the members l4 and 15 and receive ins 17 u on which rollers 18 are mounte said rol ers serving to minimize the friction between the frame and the slide block 19. Bars 20 and 21 are arranged in arallel position and receive the pins 17. Slots 22 are formed in the bars 23 have an approximately longitudinal I arrangement and hold the bars 20 and 21 apart a given distance. located intermediate of the bars 23 and are connected to the bars 20 and 21. The intermediate bars 24 each comprises comple mental members which embrace the bars 20 and 21 and are connected thereto and to one another by means of eye bolts or fastenings 25. It is to be understood that the several bars are duplicated upon opposite sides of the frame. An upright 26 is connected at its lower end to the outer end of the member 14 and its upper portion passes loosely through an opening in the outer end of the member 15. A bar 27 is attached at a middle point to the upright 26 and its end portions are bent and springs 28 connect the bent ends of the bar 27 with the outer ends of the bars 24. Channel irons 29 and 30 are fitted to the respective members 15 and 14 a l and their side members or flanges receive the pins 17. The channel irons 29 and 30,--to' gether with the bars 20, 21, 23 and 24, form a carriage which is adapted to move in and out upon the members 14 and 15, said carriage having the belt supporting arms connected therewith. The slide block 19 is of tapered or wedge form and is connected with the carriage for movement therewith. A rod or bolt 31 passes centrally through the slide block 19 and its end portions project beyond the same and terminate in eyes. U shaped rods or bars 32 embrace opposite sides of the said block and their ends are provided with eyes which. receive end portions of the rod or bolt 31, this being indicated most clearly in Fig. 3. The longitudinal portions of the rods or bars 32 pass through the eyes 25, therebv forming connection between the slide block and the carriage, whereby both move together. A cord or rope 33 is connected to the inner end of the rod or bolt 31 and after passing over a direction pulley 34 is connected at its outer end to the lever 6.

A supporting frame 35 projects laterally from the outer end of each channel iron of the carriage and may be of any construction so as to sustain the belt supporting arm and cooperating adjunctive parts. The frames 35 move with the carriage, and at the same time are either separated or brought closer together by the pivotal movements of the member 15. Wlile the slide block 19 is moved in or out, it at the same time, by reason of its tapered or wedge form, eilects an outward or inward movement of the member 15 and part Other bars 24 are to the supporting frame 35 connected di- 1 rec'tly to the part 29. Each supporting frame 35 is supplied with a belt supporting frame 36 pivoted at 37. A detent 38 is piv: oted midway of its ends upon a pin 39 and is provided at one end with a stud or projection 40 to engage with the outer end of the arm 36 i and hold the same in operative position against the tension of the drive belt. A

one end of the detent 38 away from its support, whereby the opposite end carrying the stud or projection 40 is held in the path of the arm 36. A spring 42 has connection with the inner end of the arm 36 and is designed to re turn the same to operative position after the drive belt .has cleared the same in the operation of placing the drive belt upon the drive i pulley. A cord or rope 43 connects the inner end of the upper detent with the outer end of the rod or bolt 31. A cord or rope 44 consaid rod or bolt 31 and passes around a direc tion pulley 45. As the carriage and slide block 19 move inward, the cords 43 and 44 are pulled upon and move the detents 38 to release the belt supporting arms 36, which latter turn under the tension of the drive belt and permit the latter to pass upon the drive pulley 2.

When the mechanism is in position to receive the end of the drive belt to be placed upon the drive pulley 2, the parts appear about as shown in Fig. 1 After the belt has been placed upon the inner ends of the supporting arms 36, the lever 6 is moved at its upper end to cause the operating bar 4 to carry the frame away from the axis of the 1 drive pulley and at the same time the cord or rope 33 is drawn upon to move the slide block 19 and carriage inward, thereby spreading the members 14 and 15 and 29 and 30, with the result that the belt supporting arms 36 are likewise separated. A continued movement of the outer end of the lever 6 effects an inward movement 01" the carriage and slide l block and a spreading of the belt supporting arms until. at the proper movement, which is when the parts assume the position about as shown in Fig. 1, the detents 38 are moved to latter move suddenly and release the belt, which latter glides instantly from the arms upon the drive pulley 2. At this instant the inner ends of the belt supporting arms 36 clear the outer side of the drive pulley and a the top, bottom and rear thereof, so that the belt when released from the arms is in position to pass upon the drive pulley as will be readily understood. A reverse movement of the lever 6 returns the parts to normal position.

A belt guide cooperates with the runs of the drive belt to prevent them leaving the SUI'HIO 41 normall exerts a )ressure to force nects the inner end of the lower detent with 29, thereby imparting a two-fold movement 1 drive pulley or the pulley of the machine to be driven. The guide means may be suitably supported and embody a guide 46, slide 47, pins 48 projected upward from the slide 47, grooved pulleys 49 mounted upon the pins 48, and a roller 50 for supporting the lower run of the belt and holding the same from the guide 46. A link 51 connects the slide 47 with the operating bar 4, thereby causin said slide to move in or out according as the ar 4 is drawn forward or pushed rearward. A spring 52 cooperates with the slide to assist materially in moving the same. As the bar 4 is moved rearward to bring the belt placer in position to receive the belt preliminary to placing the same upon the drive pulley, the slide 47 is moved outward. As the bar 4 is moved forward to carry the frame of the belt placer away from the axis of the drive pulley, the slide 47 is moved inward, thereby bringing the runs of'the drive belt 3 in line with the pulleys of the engine and the machine to be driven.
